This paper proposes the localization algorithm that estimates a ground position by comparing the recovered elevations estimated from aerial images with digital elevation model (DEM). The proposed algorithm consists of two stages: recovering the sampled elevations from multiple aerial images and matching them with DEM. While conventional algorithms estimate the elevation field, that is, recovere...

Painters of panoramic landscape maps use specific manual techniques to solve problems of occlusion, foreshortening and unfavourable orientation of landscape elements to the map viewer. Using digital means, the painters’ techniques may be translated into geometry deformation algorithms for digital panorama creation. This article explores the advantages and the suitability of applying local geome...

Spaceborne Synthetic Aperture Radar (SAR) interferometry has been utilised to acquire high-resolution Digital Elevation Models (DEMs) with wide coverage, particularly for persistently cloud-covered regions where stereophotogrammetry is hard to apply. Since the discovery of sand buried drainage systems by the Shuttle Imaging Radar-A (SIR-A) L-band mission in 1982, radar images have been exploite...

Encryption is an important issue in information security which is usually provided using a reversible mathematical model. Digital image as a most frequently used digital product needs special encryption algorithms. This paper presents a new encryption algorithm high security for digital gray images using genetic algorithm and Lattice Map function. At the first the initial value of Logistic Map ...

The technique of Interferometric Synthetic Aperture Radar can generate high precise Digital Elevation Model (DEM) fast, which makes it play a very important role in the development of social economy and construct of national defense. Once the high precise DEM can be acquired in real-time, the worthiness of the technique will be embodied fully. In this thesis, the research dynamic of generating ...

The 2008 Wenchuan earthquake and associated co-seismic landslide was the most recent expression of the rapid deformation and erosion occurring in the eastern Tibetan Plateau. The erosion associated with co-seismic landslides balances the long-term tectonic uplift in the topographic evolution of the region; however, the quantitative relationship between earthquakes, uplift, and erosion is still ...

Traffic simulation systems are widely used for the prediction of certain effects like traffic jam formation or the analysis of performance for new traffic light systems. Fuel consumption and CO2 emissions are important measurements. This work integrates a physical model for fuel consumption into a microscopic traffic simulation system for urban scenarios. The parameters of the model are discuss...
